Abstract

In one example, a video coding device is configured to decode a first block of video data and a second block of video data, wherein the first block and the second block share a common edge, and determine whether to deblock the common edge between the first block and the second block based at least in part on whether at least one of the first block and the second block is non-square. Non-square blocks of video data may comprise, for example, partitions (e.g., prediction units or transform units) resulting from asymmetric motion partitioning, non-square transforms for symmetric motion partitioning, or other quadtree transform splitting procedures. The video coding device may apply adapted deblocking decision functions and/or adapted deblocking filters to the common edge when either or both of the blocks is non-square.

First claim

What is claimed is:

1. A method of coding video data, the method comprising:
decoding a first block of video data and a second block of video data, wherein the first block and the second block share a common edge, wherein decoding the first block and the second block comprises reconstructing a first residual block for the first block and a second residual block for the second block;
obtaining information indicating that at least one of the first block or the second block is non-…
